Hello!

The most suitable answer is C) He was the director of the antiradicalism division in the Department of Justice.

During 1919, J. Edgar Hoover became the head of the Justice Department's Bureau of Investigation. This Bureau investigated radical groups and identified their members. Hoover's first task as the head of the Bureau was to lead the Palmer Raids with the intent of arrest and deport those people who were considered dangerous like communists, anarchists or other radicals.

Hope this helps you.

Explanation:

An special division of the Bureau of Investigation—forerunner to the FBI—accused of grouping all information on leftist radicals was fpunded by Palmer in 1919 in light of the bombs.  

J. Edgar Hoover, a Justice Department lawyer at the time, was placed in charge for the gathering. Hoover coordinated intelligence from different sources to identify those radicals most inclined to violence.
